Orientation in the white rat

T h e blind rat whose behavior had become erratic was not used in the shortened form of the maze.We utilized this animal, however, by allowing him each day to run several times through the lengthened form of the maze.I n this way, we kept the middle section constantly in use during the experiments in the shortened maze.By this means, the original smell values of this middle section were retained unaltered, for the males at least, since this blind rat was a male, and was kept in the same living cage with all the other males used in the experiment.
